Layout of workstation in new production line (English)
Abstract [sv]

Examensarbetet är utfört hos IAC Group AB i Färgelanda. Arbetet handlar om att ge förslag på en layout av en arbetsstation vid en ny produktionslina som ska tas i bruk hösten 2017.Med layout menas fysisk placering av de komponenter som ingår i stationen, så som maskiner, förvaring och arbetsvagnar etc. Detaljerna som tillverkas vid denna produktionslina är delar till en takförvaring som är en del av inredningen hos en ledande lastbilstillverkare. Redan under projektets gång monteras delar av produktionslinan och vissa testserier körs. Den arbetsstation som examensarbetet behandlar är en friktionssvetsoperation av luckor innan slutmonteringen. Då luckorna tillverkas i olika modeller behövs det bytas verktyg i svetsen mellan modellerna, dessutom är det olika förmonteringsbord i processen beroende på vilken modell av lucka som ska tillverkas.

För att arbetsstationen effektivt ska kunna ha ett genomflöde av material, samtidigt som operatörerna ska ha en ergonomiskt utformad arbetsplats behövs en noga genomtänkt layout. Processen med framtagning av denna layout har skett med metoder inom produktutveckling där koncept genereras och utvärderas. Konceptframtagningsprocessen har delvis skett i samråd med företagets handledare och produktionstekniker. Initialt genererades sex koncept som betygsattes och viktades i en matris, för att kunna välja en grundmodell. Efter val av grundmodell genererades fler koncept på en mer ingående celldesign. De sista genererade koncepten presenterades för berörd personal som till slut valde ett slutligt koncept då det uppfyllde de krav och önskemål som var satta. Examensarbetet omfattade även simulering av operatörernas arbete, analys av operatörernas balansering och förslag till eventuella förbättringar. Resultatet i rapporten beskriver det slutliga konceptet tillsammans med rekommendationer och riktlinjer från Lean production. Själva implementeringen av layouten kommer göras av IAC Group AB.

Abstract [en]

This thesis is performed at International Automotive Components (IAC) Group located in Färgelanda, Sweden. The purpose of the work is to propose a layout of a workstation in a new production line that will be launched in autumn 2017. A layout means physical location of the components in the station. The parts produced by this production line are details of a roof shelf which is part of the interior of a Swedish leading truck manufacturer. During the project, the production line is currently being assembled and some test series is run.The work station that this thesis deals with is a welding operation of the lids before transported to a final assembly. Because the lids are manufactured in different models, the weld needs replacement of tools in order to process the current part. Different assembly tables also needs to be replaced depending on the model of the lid witch is to be manufactured.

The work station needs to effectively have a flow of material, while the operators must have an ergonomically designed workplace, and that requires a carefully thought out layout. The process of preparation of this layout was done with methods of product development where concepts are generated and evaluated. The concept development process has been in consultation with the company supervisor and production. A total of six concepts were generated and they were graded and weighted in a matrix, which later led to the choosing of a basic model. After selecting the basic model were more concepts generated in a more detailed cell design. The last generated concepts were presented to the staff involved that eventually opted for a final concept when it met the requirements and preferences that were set. Part of the thesis was also to simulate the work of the operators, ensure the balancing and suggest possible improvements. The results in the report describes the final concept together with recommendations and guidelines of lean production.The actual implementation of the layout will be done by the company themselves.
